The Research Of New Three Needles Stitch Forming Jacquard Three-dimensional In The Shoes Materials Of Space Fabric

In recent decades,with the strong improvement of the domestic chemical fiber,combined with the high efficiency of warp knitting,the use of the warp knitting method was developed rapidly.Loop jacquard warp knitting fabric are many shoe companies used in the production spacer fabric shoes materials.The product profit space is quite large,but higher profit also means that the competition in the market.Companies are thinking about how to improve the human cost,the industry moving to southeast Asia,the environment deteriorating,and the market increasingly competitive.The enterprise's methods include introducing talents,upgrading industry,cutting staff,improving product quality,innovating new products and so on.Loop jacquard applied to spacer fabric shoes material on the design and development process,which using a set of corresponding type knitting jacquard CAD software can achieve some of these.The use of it can make a designer without woven,in complete loop jacquard pattern design at the same time,and you can tell in advance of jacquard fabric cloth appearance effect,which saves time,shortens the development cycle,improve the production efficiency and do not need to try small kind.Jacquard pattern woven samples consume raw materials.In textile industry,and the raw material cost is also a lot of money.In recent years,the stitch forming jacquard CAD technology is booming with the progress of computer technology,and also has created a huge value in the practical production.It can help developers to design pattern,changes process,and simulate fabric,but the stitch forming jacquard CAD which is used by companies is generally three-dimensional simulation.Because of the fierce competition,companies have to innovate,so it increases the demand for the stitch forming jacquard CAD.Now more and more designer hope to see the effect of three-dimensional simulation of the stitch forming jacquard CAD,because the simulation effect is close to the real effect,which includes color yarn,winding deformation,and pattern space form,etc.Only in this way can the designer design more complex pattern,which can create profits for enterprises.Foreign related software is expensive,and the domestic many enterprisescannot afford income to buy.But they need.Based on this demand,this paper through studying the most basic two needle flat loop model of stitch in new three stitches knitting stitch forming jacquard technology,establishes the corresponding spatial three-dimensional coordinates,then three-dimensional simulation.This paper has reached close to the real the stitch forming jacquard fabric simulation.This paper first analysis the space trajectory of 16 kinds of basic stitches structure in the stitch forming jacquard and research the loop of the tilt and migration rule.Then paper establish the corresponding mathematical model to the most basic flat stitch in jacquard knitting and the development of new three stitches knitting stitch forming jacquard system three-dimensional simulation.paper use computer graphics OpenGL and VC + + 6.0 software development tools to develop stitch forming jacquard simulation software.which is easy Finally,in the development of the system,paper study the rule about the 16 kinds of knitting jacquard stitches used to spacer fabrics,and achieve certain results,for provides designer in the industry reference to design new jacquard pattern in new three stitches knitting stitch forming jacquard.
